Hydraulic pump
Fixed displacement gear pump, 1.8 Gal/min at 2500 psi
Hydraulic pump is rated with the pump idle
When using a non-Cummins Onan pump supplied by the
customer, the hydraulic pump shaft seals must be capable
of operating in a temperature environment of 225° F to
250° F. Seal failure will result in equipment damage
